FLEAM.

SPECIFICATION forming part of Letters Patent N 0. 236,084, dated December 28, 1880.

Application filed August 18,1880. (Model.

To all whom it may concern Be it known that we, HERMANN REINHQLD and AUGUST SOHREIBER, both of Davenport city, in the county of Scott and State of Iowa, have invented a new an d valuable Improvement in Fleams; and we do hereby declare that the following isa full, clear, and exact description of the construction and operation of the same, reference being bad to the annexed drawings, making a part of this specification, and to the letters and figures of referencemarked thereon.

Figure 1 of the drawings is a representation of a vertical central section of this invention, showing one-half of the case. Fig. 2 is a perspective view of the fleam entire. Fig. 3 is a top view.

This invention has relation to fleanis; and it consists in the construction and novel arrangement of the two-part case, itsinside bladeguides, and flaring inclined lips; of the long blade-shank, its guide-pin, let-off notch, and spurred protection-notch; of the spurred trigger, the coiled operating spring having a hammer end and of the pivoted gage having three beveled facets adjustable in position for cuts of different degrees of depth, all as hereinafter shown and described.

In the accompanying A A designate the right two-part case, each of which is recessedinside to form, when the two parts are put together, a hollow case having afiattened barrel portion, B, and a disk-shaped handle portion, 0, of somewhat circular form. In the inner angle of this case the trigger-slot a. is arranged, and in its outer and rear portion is the hammerslot Z2, extending over the angle 0 of the case for the reception of the pivoted gage. Along the interior and central portion of each wall of the barrel are formed guide-ribs 61, there being two on each side, parallel with each other, and adapted to receive the guide-pin e of the blade D, whereby the blade is kept true in its stroke and prevented from twisting. At the mouth of the barrel flaring beveled faces inclining somewhat forward and having acute angular edges, to prevent slipping when the mouth of the instrument is applied to the surface of the part to be bled. The halves of the case may beriveted together or connected by screws, as indicated at g and h.

drawings, the letters and left halves ofthe lips f are formed, with The blade D is usually of dartform, double beveled on each side, and having its pointdirectly forward, in line with the center of the barrel and with the direction of the stroke. It is provided with a long shank or stem. E, flattened from side to side and extending rearwardly in the barrel, being pivoted, byits rear end, between and to the lugs of the hammer end F of the operating-spring. Two notches are formed in the under edge of the bladeshank, the first or protection notch 12, nearest the trigger, being provided with a spur, s, to engage the spur s of the trigger when the hammer portion of the spring is drawn back sufficiently to draw the point of the lance within the case. In this position the spurs s and s are interlocked, and the instrument cannot be operated by pulling the trigger. It can therefore be carried in the pocket with safety. The second or let-off notch n is angular in form,its rear wallbeing a little inclined backward and outwardto engage firmly With the trigger H. A small spring, p,is attached to the trigger to hold the latter upward against the shank of the blade.

The coiled operating-spring Gis attached by one endto a squared lug, q, of one-half of the case, formed at the central portion of the circular handle part 0. The attachment is usually made by bending the end ofthisspring in square form to fit this log. The coil of the spring winds around this lug, and the outer end, F, is enlarged and constructed in hammer form, having a striking-face, r, and .a serrated lug, t, whereby it may be pulled back wardly, increasing the tension of the spring and retracting the lance until the trigger engages with one or the other of the notches in its shank.

The gage Kis of angularform,havingthree beveled facets, z, z, and 2, arranged at difi'erent distances from the pivot h, as shown in the drawings. These facets are at right angles to the radius of adjusting motion, and receive the hammer-face squarely, adjusting themselves under the stroke if not exactly true. The position of the gage at the angle of the case is such thatit can be easilymanipulated, and it is provided with small notches 'v, to facilitate turning it around when the adjustment is being changed.

Having described this invention, what we mer end, F, pivoted to the end of the shank claim, and desire to secure by Letters Patent, E of the blade, substantially as specified. is-- 4.
